Definitions

  • the present invention relates to a pack or a stack with impregnated tissue products and a method for their production.
  • wet wipes are nonwovens that are impregnated with a generally liquid composition that contains, among other things, a disinfecting, cleaning and / or caring ingredient.
  • Wet wipes are now used in many areas of personal care and especially baby care and are very popular because they offer the possibility of quick and convenient cleaning or care without the need for additional water. But wet wipes are also popular in the cleaning sector, especially for surface disinfection.
  • Impregnated pads are also nonwovens impregnated with a liquid composition, which as a rule differ from wet wipes only in their different format and, if necessary, in a higher material thickness of the nonwoven. Just like wet wipes, they offer the advantage of a convenient cleaning option that is generally available everywhere, be it for disinfecting surfaces or objects or for daily personal care. for example to remove make-up.
  • Both soaked pads and wet wipes are usually packaged in handy units of approx. 10 to 200 wipe products.
  • a disadvantage of this type of packaging is that an uneven distribution of the impregnating agent in the packaging is often observed. Because in the stack of impregnated cloth products contained in the packaging, the impregnating agent sinks due to gravity after a comparatively short standing time, so that the cloth products located at the top of the stack no longer contain sufficient impregnating agent, while the cloth products located at the bottom of the stack contain an unnecessarily large amount of impregnating agent or are surrounded by too much impregnation agent. This limits the usability and in particular the effectiveness of the tissues located at the top of the stack.
  • An alternative approach provides for the use of an impregnating agent with increased viscosity in order to reduce "sagging" of the impregnating agent in the pack.
  • the increased viscosity is achieved by thickeners.
  • This approach also has various disadvantages, because thickeners impair the effectiveness of many impregnating agents.
  • residues form on surfaces and, in addition, a larger amount of impregnating agent is required in order to adequately wet a surface to be cleaned.
  • the EP 0 978 247 A1 describes a stack of impregnated wipes, which contains one or more evaporation protection layers between the impregnated wipes, by means of which the evaporation of volatile constituents of the impregnating agent is to be prevented.
  • the evaporation protection layers are not necessarily impermeable to liquids.
  • the evaporation protection layers are preferably hydrophobic and consist of polyethylene or polypropylene. However, this represents an additional burden for the environment, since these materials are not biodegradable, but are produced several times in each package as waste to be disposed of.
  • the DE 10 2006 035 570 A1 describes a pack with disk-shaped or pad-shaped fiber composite articles, each comprising a fiber fleece layer soaked with a soaking liquid and a liquid-impermeable film layer that prevents liquid migration to the floor and evaporation and gives the article dimensional stability.
  • this solution fulfills the purpose of reducing the sagging behavior of the impregnating agent in a pack, it has the major disadvantage that the production of such fiber composite articles involves significantly increased effort and costs.
  • the use of an increased amount of impregnating agent should be avoided and the solution should preferably be equally suitable for all known nonwoven materials, i.e. both natural fibers and synthetic fibers, and pollute the environment as little as possible.
  • the invention solves this problem with the features of the claims and in particular by providing a stack of towel products or a pack of towel products (so-called "flow pack") containing a stack which comprises a plurality of towel products arranged on top of one another, the towel products each having one comprise an impregnating agent impregnated nonwoven, and wherein in the stack comprising the cloth products arranged on top of one another, at least one barrier layer is also arranged, which comprises a material or consists of a material which has a different absorbency for the impregnation agent than the nonwoven fabric which the Cloth products comprise, and wherein the material that comprises or consists of the at least one barrier layer is a liquid-impermeable film made of biodegradable and / or compostable plastic.
  • a wipe product is understood to mean, in particular, a pad or a wipe made of nonwoven material which can be soaked with a liquid composition.
  • the impregnated towel products stacked according to the invention are also arranged on top of one another and optionally folded, for example in that a layer of towel product engages in each case with the overlying and the underlying layer of towel product.
  • the stack of towel products according to the invention contains at least one barrier layer with or made of a material which has a different absorbency than the non-woven fabric which the towel products comprise. The barrier layer prevents the impregnating liquid from settling on the surface due to gravity Bottom of the pack or the stack accumulates because it is impermeable or substantially impermeable to liquids.
  • the number of barrier layers provided for a pack of towel products and their positioning within the stack of towel products can be freely selected and should in particular be made dependent on the number of towel products contained in the stack. In small stacks of, for example, 10 towel products, a barrier layer placed between each 5 of the towel products may be sufficient. In this way, a liquid gradient forms above and below the barrier layer in the towel products contained in the stack, but because the barrier layer is impermeable to the impregnating agent, it is significantly lower than the liquid gradient in a corresponding stack of towel products without an intervening barrier layer.
  • the arrangement of several barrier layers within the stack of tissue products is advisable, for example at a distance of 5, 10, 20 or 50 tissue products.
  • the material that comprises the at least one barrier layer or of which it is made has a lower absorbency than the nonwoven fabric that the towel products comprise, the barrier layer being impermeable or substantially impermeable to liquids.
  • the liquid-impermeable material that comprises the at least one barrier layer or of which it is made is, according to the invention, a film made of biodegradable and / or compostable plastic.
  • the biodegradable and / or compostable plastic is selected from the group consisting of thermoplastic starch, cellulose, degradable polyesters, polylactide, seaweed, chitin, chitosan, lignin or mixtures of these or one or more of the aforementioned materials.
  • a barrier layer can be contained several times per pack depending on the size of the pack of towel products or depending on the amount of towel products contained in a pack, increased waste is created in each pack due to the barrier layers contained, which, however, due to the biodegradability or compostability of the liquid-impermeable film does not represent any additional pollution for the environment. Rather, the use according to the invention of biodegradable or compostable barrier layers in a pack of cloth products has the additional benefit Environmentally friendly effect that due to the more uniform distribution of liquid in a pack of wipe products due to the at least one barrier layer contained, fewer and preferably no wipe products are contained in a pack that contain too little impregnating agent, i.e. are too dry for the desired application, and are therefore unused must be disposed of.
  • the stack contained in a pack of cloth products according to the invention comprises several layers of cloth products arranged one above the other, which are separated by a barrier layer from several further layers of cloth products arranged one above the other.
  • the stack contained in a larger pack of cloth products preferably comprises several barrier layers which are spaced apart from one another by one or more layers of cloth products arranged one on top of the other.
  • a pack of tissue products according to the invention contains a stack in which soaked tissue products are arranged alternately with barrier layers, i.e. a layer of barrier layer is arranged on each layer of tissue product, on which in turn a layer of tissue product is arranged.
  • barrier layers i.e. a layer of barrier layer is arranged on each layer of tissue product, on which in turn a layer of tissue product is arranged.
  • a pack of cloth products according to the invention contains a stack in which several layers of cloth product arranged one on top of the other, for example 2-20 layers of cloth product, more preferably 3 to 15 layers of cloth product and particularly preferably 5 to 10 layers of cloth product through a layer of barrier layer of in turn several layers of cloth product arranged on top of one another, for example 2-20 layers of cloth product, more preferably 3 to 15 layers of cloth product and particularly preferably 5 to 10 layers of cloth product, are separated.
  • each impregnated cloth product contained in the stack contains a sufficient amount of impregnating agent so that the impregnated cloth products, regardless of whether they are arranged at the top or at the bottom of the stack, can reliably offer the desired cleaning success.
  • the present invention is suitable without restriction for all nonwovens. Therefore, the nonwoven that is contained in a stack according to the invention of impregnated cloth products or in a pack according to the invention with impregnated cloth products can be a conventional nonwoven, in particular a nonwoven made of viscose fibers, polypropylene fibers, lyocell fibers, PET fibers, microfibers, cotton - Fibers or mixtures thereof or consists thereof.
  • the nonwoven which is contained in a stack according to the invention of impregnated cloth products or in a pack according to the invention with impregnated cloth products consists of viscose fibers and / or Lyocell fibers and / or PET fibers, ie it can either be 100% Viscose fibers, Lyocell fibers or PET fibers, or they consist of mixed fibers.
  • the nonwoven fabric optionally also contains microfibers and / or cotton fibers, for example in a proportion of up to 20% by weight each, in particular 0.1-5.0% by weight.
  • the nonwoven fabric contained in a stack according to the invention of impregnated cloth products or in a pack according to the invention with impregnated cloth products consists of viscose fibers and / or Lyocell fibers and / or PET fibers and / or hemp fibers and / or cellulose fibers and / or flax fibers, and optionally also from 0.1-20.0% by weight microfibers and / or 0.1-20.0% by weight cotton fibers.
  • the nonwoven which is contained in a stack according to the invention of impregnated cloth products or in a pack according to the invention with impregnated cloth products comprises or consists of 30-70% by weight viscose fibers and 30-70% by weight PET fibers and optionally 0.1-5.0% by weight microfibers and / or 0.1-30.0% by weight cotton fibers.
  • the proportion of viscose fibers to PET fibers can vary continuously, for example from 1% by weight viscose fibers / 99% by weight PET fibers to 99% by weight viscose fibers / 1% by weight PET fibers.
  • the impregnated wipe products contained in a stack according to the invention or a pack according to the invention can be impregnated with any impregnating agent, the impregnating agent being in particular a composition based on water, oil or alcohol, an oil-in-water emulsion or a water-in-oil -Emulsion can be and / or is selected in particular from the group that comprises or consists of cosmetic compositions or preparations, cleaning agents and disinfectants.
  • Cosmetic compositions or preparations are understood to mean all types of liquid cosmetic compositions or preparations, including agents for facial and / or body cleansing and care, de-makeup, face masks, cures, skin care agents, cosmetic agents and agents that contain a medicinal or cosmetic active ingredient
  • the active ingredient can be, for example, a compound with nourishing, greasy, moisturizing, soothing, moisturizing, anti-inflammatory, regenerative, wound healing, invigorating, firming, blood circulation-promoting, antimicrobial, fungicidal, bactericidal, antiallergic and / or antibacterial properties.
  • Cleaning agents are understood to mean both agents for cleaning the body and agents for cleaning surfaces, e.g. floors.
  • Disinfectants are understood to mean both skin disinfectants, in particular hand disinfectants, and surface disinfectants.
  • the at least one barrier layer also contained in the pack of tissue products according to the invention is not accidentally used by users like a soaked tissue product for cleaning, etc.
  • the at least one barrier layer optionally differs optically from the tissue products, in particular by a different color.
  • the invention also relates to a method for producing a pack of tissue products containing a stack which comprises a plurality of tissue products arranged one on top of the other, each comprising a nonwoven fabric soaked with an impregnating agent, wherein in the stack comprising the tissue products arranged one on top of the other also at least a barrier layer is arranged which comprises a material or consists of a material that has a different absorbency than the nonwoven fabric which the towel products comprise, wherein the at least one barrier layer is a liquid-impermeable film made of biodegradable and / or compostable plastic.
  • a plurality of layers of cloth products arranged one on top of the other are preferably arranged between two barrier layers, the barrier layers and the cloth products together forming the stack.
  • two layers of barrier layer for example, 2 to 20 layers of cloth products, in particular 3 to 15 layers of cloth products and particularly preferably 5 to 10 layers of cloth products, can be arranged.
  • the cloth products, nonwovens, impregnating agents and barrier layers used in the method according to the invention can in particular be designed as described above with reference to the pack according to the invention with cloth products or the stack with cloth products.
  • the stack 1 has a multiplicity of towel products 2 which are arranged in layers on top of one another.
  • the towel products 2 can be arranged horizontally on top of one another lengthwise or partially folded into one another, for example by folding a layer of towel product 2 on one side into the layer of towel product 2 lying above and folding it into the layer of towel product 2 below on the opposite side .
  • the stack 1 After five layers of cloth product 2 arranged one on top of the other, the stack 1 has a barrier layer 3 which consists of a liquid-impermeable material. In this way, impregnating agent emerging from the impregnated wipe products and flowing down under the force of gravity can flow down a maximum of four layers in the pack until it is stopped by the barrier layer 3.
  • a liquid gradient is only formed between the five layers of cloth products 2 arranged between the barrier layers 3 , but not (as in the prior art) between all of the layers of cloth product 2 contained in the pack State of the art observed, and the barrier layers 3 (arranged at regular intervals in the embodiment shown) ensure that all of the tissue products 2 arranged in the pack or in the stack 1 are still soaked with sufficient impregnating agent even after a period of standstill.
  • Example 1 Investigation of the sagging behavior in a pack according to the invention with cloth products
  • tissue products 2 nonwoven: 100% PET
  • an amount of impregnating agent of 4.5 g per gram of nonwoven.
  • the stack 1 of a total of 100 impregnated wipe products with the barrier layers in between was left to stand for 55 hours.
  • the sagging behavior of the impregnating agent in the stack 1 was then examined by always removing the top 10 wipes from the top of the stack 1 and weighing them.
  • Table 1 Investigation of the sagging behavior in a pack according to the invention with cloth products Number of cloths Amount of liquid [g] Liquid gradient 10 94.93 1.59 20th 115.7 30th 112.29 40 127.54 50 103.09 60 125.48 70 103.52 80 132.59 90 120.19 100 150.66
  • the liquid gradient was determined both in the case of the pack according to the invention with tissue products 2 and in the case of the reference pack. This is defined as the quotient of the amount or weight of impregnating agent in the top ten layers of cloth products 2 and the amount or weight of impregnating agent in the bottom ten layers of cloth products 2 in stack 1.
  • a liquid gradient of 1.59 was determined and a liquid gradient of 2.25 was determined for the reference pack with cloth products 2.
  • the barrier layer 3 improves the Absack in a package with tissue products 2 significantly by all wipe products 2 contained in a pack contain a fully sufficient amount of impregnating agent even after a prolonged service life. This is not the case in a pack without a barrier layer 3, as can usually be found in the prior art, because with a liquid gradient> 2, the upper wipe products 2 of a pack contain only an insufficient amount of impregnating agent, while the lower ones Towel products 2 in one pack contain too much impregnation agent. The upper towel products 2 therefore often have to be disposed of unused, since they do not contain enough impregnating agents for the desired application.
  • the excess impregnating agent that collects at the bottom of the pack must likewise be disposed of unused in packs not according to the invention without a barrier layer, so that the environment is polluted both by unused impregnating agent and by unused cloth products. This is avoided by the present invention.
